"I was selling a 71 year old home and the inspection revealed a failing septic system. I had called another company as well as Bob snd had opted to use the other company which was local in Merrimack. Sadly I was told it would be 6 to 8 weeks. I could not wait that long since the house needed to be sold before winter. I called Bob and he began the same day! He explained he was also an engineer and could do the required septic design himself. He was able to have the entire job done in 2 weeks and we had a contract to sell before he finished. He was a delight to work with and I woukd recommend this company without any hesitation."

"Excellent. I called Ferris Plumbing on a Thursday afternoon and left a message. Matt returned my call the next morning. After I explained the problem, Matt said he would try to get to me that day (Friday), but he may not be able to. Meanwhile, he suggested not using that toilet. He called later that day and said he couldn't make it, but would be able to on Monday. He called me on Monday morning to confirm that he would be coming and gave me a estimated time of arrival. Matt wasn't able to come himself, but two of his plumbers arrived mid-morning. I explain all of this because Matt's communication was OUTSTANDING. I always knew the status and I knew he would be arriving as soon as he could. His two plumbers were also excellent and efficient. They replaced the toilet flange and gasket, and remounted the toilet without needing to disturb the downstairs ceiling. I should mention that the toilet is the original installation of 48 years ago. The original gasket was completely disintegrated to the point that only few small fragments of it were left. They were also very careful to protect the carpet just outside the bathroom by placing a drop cloth to protect it. Their service and work was EXCELLENT. We are considering remodeling that bathroom and Ferris Plumbing will certainly be our first choice to do the work. I highly recommend (Matt) Ferris Plumbing."
